UNITED STATES BENJAllIlN F. LANDIS, OF ST. JOSEPH, MISSOURI.

BOBBIN.

SPECIFICATION forming part of Letters Patent No. 305,935, dated September 30, 1884?. Application filed April 21,1884. (No model.)

To ctZZ whom it may concern:

Be it known that I, BENJAMIN F. LANDIS. a citizen of the United States, residing at St. Joseph in the county of Buchanan and State of Missouri, have invented certain new and useful Improvements in Bobbins, of which the following is a description.

This invention relates to that class of bobbins which are used to carry thread in the shuttles of sewing-machines. 850., and its object is to so construct and wind a long bobbin with thread that it will give off the thread at a point near the center of the bobbin with less side draft on the thread than is usual to long bobbins. A bobbin of the class under consideration gsually consists of a body having a flange or head at each end, and the thread is usually wound in even layers from end to end on the body of the bobbin. In using the thread oil from such a bobbin in a shuttle, the thread, passing from a central hole in the side of the shuttle, will gradually traverse-the whole length of the bobbin, thus To obviate this my invention consists in the construction and combination of parts form: .ing abobbin, andin the method of winding the same, hereinafter described and claimed, reference being had to the accompanying drawings, in whichlligure 1 represents one form of my bobbin Fig. 2- represents the same only partly filled with thread. Fig. 3 represents the same with the thread partly used off, and Fig. 4 is a transverse section of a modification of the same. Fig. 5 represents a modiiieation.

A. represents the spindle, which is necessarily a part of my bobbin. This spindle. may be a mere stiff wire, which is the usual form that I expect to give it; or it may be hollow to fit onto another spindle. In thelatter case a stiff paper quill or hollow spindle, a, will answer the purpose.

B and 0 represent two spools bored to turn freely and to slide freely endwise on the spindle A, or quill a, whichever it may be convenient to user The spools have flanges I), as usual. The lengthof each spool is about one-third the interior length of the chamber in the shuttle.

In winding this bobbin, one of the spoolssay Bis placed on a spindle near one end and wound full. Then the thread is wound quickly across the open space on the spindle between the two spools onto the spools O, and that is filled. Then the space between-the two spools is wound full, the thread is cut and fastened, and the bobbin is complete.

This bobbin, either having a wire or a quill spindle, may be furnished by the thread manufacturer and placed on the market the same as con'nnon spool-thread is now done.-

In use, the bobbin is first placed in the shuttle and the thread drawn from the central side hole thereof. Then the thread will first be unwound from the space between the spools, having to traverse only one-sixth the length of the spindle each side of the hole in the shuttle. Then spool G will be drawn by the thread to slide along the spindle in front of the hole. New, this spool, moving freely endwise on the spindle,will adjust itself to the strain of the thread until the thread draws .lmost directly to the hole all of the time, and when this spool is emptied the thread will draw the spool 13 in front of the hole in the shuttle in a similar manner, crowding away the empty spool G. I D

As the combination of such a bobbin with a shuttle is the subject of another application for a patent by myself, I do not here claim it. Such bobbins may be used in shuttles for weaving as well as for sewing. If it were an object, there mightbe more than two spools on each spindle similarly wound.

That portion of the spindle on which the spools are placed maybe made square, so that the spindle must revolve with the spools; but the spools must be fitted free enough to slide endwise on the spindle the spindle revolving on its'own journals in the shuttle at theeuds of the spools. On the same principle I may use a single spool at one end of the spindle and then wind the thread onto the uncovered portion of the spindle at the other end, accomplishing the same purpose to some extent.

The bobbin herein described is the subject of another application, Serial No. 101,897, filed July 25, 1883, in combination with it shuttle for its use. 5 WVhat I claim as my invention, and desire to secure by Letters Patent, is

As an article of manufacture, a bobbin consisting' of a spindle, a spool thereon, and a BENJAMIN F. LANDIS.
